A broad, locally hosted MyFitnessPal MCP server with 20 tools covering diary reads and writes, food search, custom-food management, body measurements, exercises, nutrition goals, water and fasting writes plus nutrition reports, with Chromium browser auto-discovery for authentication. It is not an official project: MyFitnessPal has no public API, reads are scraped, and writes rely on undocumented internal endpoints that can change at any time; the README also states plainly that legacy form login mostly fails after MFP's move to NextAuth, so browser-session cookies are the reliable path. Suitable for individuals who accept those constraints; not suitable where official support or policy certainty is required, or where storing session cookies locally is unacceptable.

MFP_USERNAME
Your MyFitnessPal email; optional legacy credential auth (largely deprecated), can be plain or Fernet-encrypted.
MFP_PASSWORD
Your MyFitnessPal password; optional legacy credential auth, best stored Fernet-encrypted.
MFP_SECRET_KEY
Fernet key used to decrypt encrypted credentials; keep it in a shell env or the OS keychain (service mfp-mcp), not in the config file.

Shown for Claude Desktop. Other clients may use a different file or key (VS Code uses "servers") — the configurator below converts it.

Goes in your project's .vscode/mcp.json (VS Code uses a "servers" key).

Run it in a terminal; replace any <…> placeholders with your own values first.
After completely restarting Claude Desktop, a hammer icon should appear; ask "Show my MyFitnessPal diary for today" — returned diary data proves the connection works.
Once connected, you can ask your AI assistant things like:

A locally hosted Model Context Protocol server that lets AI assistants such as Claude interact with your MyFitnessPal data: food diary, exercises, body measurements, nutrition goals, water intake and intermittent fasting. MyFitnessPal has no public API: reads are scraped from the website via python-myfitnesspal, diary writes go through MFP's internal v2 JSON API (the same one its web client uses, authenticated with your existing session token), and custom-food writes use a different family of cookie-authenticated web endpoints. The server runs locally over stdio; data is only transmitted between your machine and myfitnesspal.com.
